Lightning strikes pose a threat to the operation of railway traction substations, often causing equipment damage and power supply interruptions that compromise operational safety. With the advancement of railway intelligence, the limited overvoltage resilience of secondary equipment means that traditional lightning protection methods can no longer meet industry requirements.

Railway authorities issued regulatory documents such as *Circular on Transport and Supply Equipment [2017] No. 240* to drive the standardization of railway lightning protection.

Aligning with relevant railway technical standards, Anhui Jinli develops customized lightning protection solutions for numerous traction substations. Its proprietary products—including surge protective devices and signal lightning arresters—effectively discharge lightning currents and suppress overvoltage, ensuring the stable operation of on-site monitoring, control, and communication equipment. These products strictly adhere to railway specifications, have been proven effective in real-world thunderstorm conditions, and are widely used across the high-speed rail, electric power, and petrochemical sectors.

For the Guangxi Yucen High-Speed Railway project, Jinli leveraged its technical expertise in railway communication protocols to integrate lightning protection equipment into a unified monitoring platform. This enabled the lightning protection system to be visualized and controlled, reduced the operations and maintenance burden, and achieved a technical upgrade from isolated point-based protection to coordinated system-wide protection.

Addressing future railway construction scenarios characterized by high-altitude and heavy-haul operations, Anhui Jinli focuses on on-site requirements to enhance product reliability and intelligence. The company drives the shift from passive lightning protection to active monitoring and early warning, consistently delivering customized, comprehensive lightning protection solutions to safeguard railway transport safety.
